Do We Have This One?? A reversal of So Last Season: It's a difficult fight against the Big Bad, and the hero's newer, more powerful powerups and weapons have been destroyed, damaged, or rendered useless. What's a hero to do? Go back to where the started, using the weapon or Finishing Move they used to use in the beginning of the show. And what do you know? Despite having been reduced to The Worf Barrage twenty-five episodes ago, it works! Definitely connected thematically to Where It All Began and a subtrope of Book-Ends. Compare Bag of Spilling.
